説明

In order to measure accurately the ultrasonic speeds in liquids under pressure, a new experimental apparatus was constructed employing a sing-around method.<br>The ultrasonic speeds in benzene and toluene were measured at temperatures of 293.15, 298.15 and 303.15K, and pressures up to 160MPa. By measuring the pressure variations of ultrasonic speeds in benzene, the reliability of apparatus was confirmed to be better than ±3msec-1.<br>From the experimental results of the pressure dependence of ultrasonic speeds, the densities under high pressure were calculated. The calculation method was improved in part from that published previously. The densities thus obtained agreed well with the experimental values reported in the literature within approximately 0.2 per cent over the range of pressure up to 160MPa, and the improved calculation method of density was found to be good, especially in higher pressure region.
